电铸复制是制造用于太空、实验室和同步加速器实验的全壳掠入射镜的基本技术。针对 X 射线天文学，开发了一种镍电铸复制工艺，用于生产轻质且高分辨率的 X 射线反射镜。此外，用于制造同步加速器实验的X射线镜的电铸工艺在过去十年中也取得了显着的发展。我们预计，使用地面电铸复制工艺生产 X 射线天文学光学器件将进一步提高 X 射线望远镜的性能。本文介绍了我们在镍电铸复制工艺方面正在进行的开发工作，包括试点研究的结果。
Electroforming replication is an essential technique for fabricating full-shell, grazing-incidence mirrors for use in space, laboratories, and synchrotron experiments. For X-ray astronomy, a nickel electroforming replication process was developed and is used to produce lightweight and high-resolution X-ray mirrors. In addition, the electroforming process for fabricating X-ray mirrors for use in synchrotron experiments has undergone remarkable development over the past decade. We expect that the use of the ground-based electroforming replication process for the production of optics for Xray astronomy will lead to further improvements in the performance of X-ray telescopes. This paper describes our ongoing development efforts in the nickel-electroforming replication process, including the results of a pilot study.
